Therefore he needs a ruler who acts as a Hakm, or arbiter, whose verdicts are fair and above all personal considerations and is infallible.Such a Hakm can only be identified and put in place by none other than the Great Creator, Allah. Therefore it is cardinal that the Nabi and the Imams are mansus-min-Allah or selected and appointed by Almighty Allah. The Second Benefit: Mu’jizah Or Miracle As a proof of Prophethood, the Prophets’ present miracles to the people.

These miracles are incredible happenings that the commoners are unable to perform. For example: converting the staff into a snake, making the dead alive, breaking the moon into two etc… etc… When a person claims to be the messenger of God and performs miracles as a proof, then there will not remain any doubt as to his veracity. To the contrary, when an imposter claims that he is a prophet, then it is impossible that Allah would provide him the means of performing any miracle.

As people believe in the veracity of a Prophet by witnessing the miracles, so also people believe in him by hearing about the miracles through authentic sources. It is just like people who have not seen a city, say for example Mecca, believe in its existence only on hearing about it from others. The Third Benefit: The Prophethood Of The Last Messenger The Prophet (S) of the last epoch, the cause of the creation of the Universe Mustafa(S), has manifested innumerable miracles.

Besides all those miracles the most prominent is the Holy Qur’an that he had presented to his followers as a miracle after declaring himself the Prophet of Allah. He had challenged the erudite scholars of the day to present a book equal in quality, or even a verse equivalent to any of the verses of the Qur’an. None of the scholars of that time was able to meet the challenge but in frustration, they prepared to fight with the Prophet and his supporters.

Bin Babawia relates that Ibnal Sakeet, a renowned scholar went to Imam Ar-Ridha’ (as) and asked him that Allah had given to Musa (as) the Staff and the Shining Hand (Y ad al-Baidah ), to prophet ‘Isa (as) and the miracle of healing and what miracles had Allah given to our Prophet (S). Imam Ar-Ridha’ (as) replied that when Allah gave Prophet hood to prophet Musa (as), the art of magic was at a peak. There used to be competitions of the magicians those days.

Therefore prophet Musa (as) was provided with a miracle that could subdue the magic of those masters.
